Hello. I've already made a post about this a little under 7 months ago, but received no replies. I think I could've been a little bit more clear.
Simply put: I love music, I want that music to sound as best as possible. I know I can get the most out of my headphones than what is provided by default, so in Windows and Android I can use equalizers and bass boosters to enhance the audio system-wide. If I were to ask how to do this in Ubuntu, I'd probably be told to use PulseAudio-Equalizer.
Ok, then. I'd install it from the Webupd8 PPA, launch it, and turn the EQ on. I'd first raise the lower frequencies, and that's where the problem begins. Even the slightest raise produces awful distortion/software clipping. It makes my listening experience unenjoyable at best.
Unfortunately, PA-EQ is the only option I have. It is a very old and unmaintained piece of software that performs below expectations. There is at least one other person (Naike) with this problem, probably much more. Why do I say this? I've had this same problem with four different sound cards on four completely different motherboards.
So we must do something about this! I miss having deep bass and clear treble, and I'm sure others would love to have nice audio with Ubuntu that lives up to the capabilities of their hardware.
I'm running Ubuntu 12.10 with pulseaudio 2.1 and pulseaudio-equalizer 2.7. I'd love to get some help with this. Please be sure to read my old post if you need more info. The versions are different but the problem remains the same. Thanks!
